1. What is the total resistance of a circuit called?

A Equivalent resistance B Absolute resistance C Unlimited resistance D Comprehensive resistance

2. Which of the following best describes resistors connected in parallel?

A Resistors connected across from one another B Resistors connected end-to-end C Resistors that connect to capacitors D Resistors that aren't in the same circuit

3. Which of the following best describes resistors connected in series?

A Resistors connected across from one another B Resistors connected end-to-end C Resistors that connect to capacitors D Resistors that aren't in the same circuit

4. What formula would be used to calculate the equivalent resistance if R1 and R2 were connected in series?

A R = R1 + R2 B R = R1 * R2 C R = 1/R1 + 1/R2 D 1/R = 1/R1 + 1/R2

5. What formula would be used to calculate the equivalent resistance if R1 and R2 were connected in parallel?

A R = R1/R2 B 1/R = 1/R1 + 1/R2 C R = R1 * R2 D R = 1/R1 + 1/R2

6. What is the equivalent resistance of two 10 ohm resistors in series?

7. What is the equivalent resistance of two 10 ohm resistors in parallel?

A 5 Ohms B 20 Ohms C 30 Ohms D 10 Ohms

8. What is the equivalent resistance of three 30 ohm resistors in series?

A 40 Ohms B 90 Ohms C 3 Ohms D 10 Ohms

9. What is the equivalent resistance of three 30 ohm resistors in parallel?

A 10 Ohms B 3 Ohms C 40 Ohms D 60 Ohms

10. When you have a circuit with both series and parallel resistors, what do you do first when calculating the equivalent resistance?

A The series resistors B The parallel resistors C It doesn't matter which you do first
